Norway’s Corvus Energy revealed this week an order from Finland’s Wartsila for four energy storage systems. Wartsila will install this equipment on LNG-powered platform support vessels operated by Louisiana-based Harvey Gulf.
The orders follow the sea trial of Harvey Energy, the first LNG-battery hybrid retrofit of a PSV in the Americas.
Additionally, Wartsila will integrate the battery-based ESSs, each with a capacity of 745 kWh, into their LNG-fueled hybrid-electric propulsion system.
Corvus Energy says the ESS and Wartsila energy management system will allow the vessels to operate in dynamic position mode on a single engine augmented by battery power.
Moreover, it will help the ships to operate more efficiently in transit and other operational modes and to operate on battery-power only when stationary.
Wartsila again selected Corvus Energy’s Orca Energy ESS as the battery type for this application.
Furthermore, the four LNG-battery hybrid vessels Harvey Liberty, Harvey Power, Harvey Freedom and Harvey America will feature the 1100VDC – 745 kWh ESSs.
US privately-owned firm Harvey Gulf plans to put the ships into service in early 2022.
